Biohazard Symbol Uncovered: Why It’s the Most Recognized Danger Icon on Earth When it comes to safety and hazard communication, few symbols resonate as powerfully and universally as the Biohazard Symbol. Known globally as the iconic green triangle with a red border and pointer, this simple yet striking icon has become the most recognized danger symbol across industries, healthcare facilities, laboratories, and public spaces worldwide. But what makes this symbol so unmissable—and why has it earned its place at the top of the hierarchy of danger icons? ### The Origin of the Biohazard Symbol The Biohazard Symbol was developed in the 1960s during a period of growing public awareness around scientific risks, particularly centered on infectious diseases and biological materials. Originally created by the American Biological Control Association and later refined by the United Nations and international safety organizations, the symbol was designed to warn personnel, patients, and the public about exposure to potentially infectious or hazardous biological agents.
